Best deal on Donnie Darko?

I saw this movie for $22.99 at Best Buy, does anyone know where to find it any cheaper than that? I have this unsettling urge to buy it now but want to know if it's cheaper before I sucomb to Best Buy's asking price. Also if anyone knows of a good deal on The Sapranos Second Season feel free to let me know about that one too. My dad's b-day is coming up . Thanks
